Specification of Letters Patent.

Patented Feb. 20, 1917.

Application filed April 1]., 1916. Serial No. 90,332.

T all whom it may concern.

Be it known that 1, WILLIAM D. BERRY, a citizen of the United States, residing at Florence, in the county of Lauderdale and State of Alabama, have invented certain useful Improvements in Mail-Carriers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a mail carrier, and has special reference to a type of carrier mounted upon a cable so that the receptacle containing the mail may be provided with propelling means to convey the mail to and from given points, one'object of the invention being the provision of peculiar construction of receptacle and guiding and supporting structure therefor, the motor and propelling means being carried by the struc: ture.

A further object of this invention is th provision of a spring motor mechanism which will provide propelling means for transporting mail from one point to another, as for instance from a point of delivery by a rural mail carrier to a farm house, and vice versa.

A still further object of this invention is the provision of a simple, durable and inexpensive device of this character, which is thoroughly useful and practical, and easily installed.

In the accompanying drawings Figure 1 is a view on reduced scale, showing the two cables, two posts and the present carrier in position thereon.

Fig. 2 is an end view of the-carrier.

Fig. 3 is a side elevation thereof from the A cable engaging side thereof.

Fig. 4 is an enlarged detail sectional view of the motor and transmission mechanism.

Fig. 5 is a view of a modified form.

Referringto the drawings, the numerals and 11 designate respectively-the house post and the road post, between which is strung the cable 12, the two bumpers or shock absorbers 13 and 1 1 being carried to the posts. 1

The carrier 15 consists of the receptacle 16 which may be of any desired construction, and is carried by the hanging structure 17 which has journaled therein the lower shaft 18, having connected thereto the spring motor 19, of any preferred construction. The receptacle is provided with the two steadying wheels 20. The shaft 18 has fast thereto the large gear 21, which'meshes at all times with the pinion 22, mounted upon the intermediate shaft 23. This horizontal. shaft 23 is slidably mounted for longitudinal and rotary movements in the sides of the structure 17, and has fast thereon the two oppositely disposed bevel gears 24 and 25, the operating handle 26 being connected to one projecting end ofthe shaft 23 to shift and hold the shaft 23 in the desired adjustment.

A vertical shaft 27 is mounted in a horizontal bridge bar 26 secured to the side walls of the structure 17 and carried upon the lower end of the shaft is the bevel pinion 28 which is adapted to be engaged by one or the other of the gears 24: and 25,

this engagement causing the shaft 27 to be rotated in a forward or reverse direction, according to the direction of movement to be given to the carrier. Upon the upper end of the shaft 27 is a bevel pinion 29, which is in mesh at all times with the gear 31 of the driven shaft 30, whose cable engaging pulley 32 is the tractor wheel and engages the upper cable to pull the carrier in either desired direction.

Where found necessary and desirable, the structure '17 may be as long as the receptacle, and two driven shafts as with the traction pulleys may be employed, it being merely necessary to connect the shafts with a sprocket and chain to insure rotation in the desired direction and in unison.

In Fig. 5, the reversible shaft 27 carries a large bevel gear 34; that meshes with the gear 35 on shaft 36, while the friction wheel 37 transmits motion through the friction wheel 38 to the shaft 30 that carries the tractor pulley 32.

From the foregoing description, it is evi- I dent that with a mail carrier constructed in In this way, an apparatus of simple con-' struction. may be provided for delivering mail to and from the rural mail man and the farm house, and thus render it unnecessary for either to'go to any great trouble,

ill

and at the same time it will save time and labor in the delivery and collection of mail.

What I claim as new is:

In a mail carrying device, an elevated cable track, a mail receptacle, a hanger structure connected to the upper surface of the receptacle, a horizontal shaft rotatably mounted in the sides of the structure, a spring motor for rotating the shaft, a large gear carried by the shaft, a traction Wheel shaft journaled in the sides of the structure adjacent the top, a traction wheel carried by the shaft and mounted on the cable track, a bevel gear carried by the traction shaft, a horizontal bridge bar in the structure, a vertical and rotatably mounted stub shaft journaled in the bar, beveled pinions car ried upon the respective ends of the stub shaft, one of the pinions being arranged in. mesh with the beveled gear, a horizontal shaft slid-ably and rotatably mounted in the sides of the structure between the drive shaft and the stub shaft, a pinion carried by the sliding shaft and meshing at all times with the large gear, opposed beveled gears carried by the sliding shaft and arranged in proximity to the other beveled gear on the stub shaft, and a handle carried by the projeeting end of the sliding shaft whereby to place either of the beveled gears in mesh with the adjacent beveled pinion to consequently cause the device to move in either direction on the track.

In testimony whereof I aflix my signature.

WILLIAM D. BERRY.
